Evaluation of Release Consistent Software Distributed Shared Memory on Emerging Network Technology
"... We evaluate the effect of processor speed, network characteristics, and software overhead on the performance of release-consistent software distributed shared memory. We examine five different protocols for implementing release consistency: eager update, eager invalidate, lazy update, lazy invalidat ..."

independent of the protocol used. Medium-grained applications, such as Water, can achieve good performance, but the choice of protocol is critical. For sixteen processors, the best protocol, lazy hybrid, performed more than three times better than the worst, the eager update. Fine-grained applications
A medium-grain reconfigurable cell array for DSP application
- in Proc. 3rd iasted International Conference on Circuits, Signals, and Systems, Cancun
, 2003
"... Digital signal processing (DSP) is an essential component of many applications, including multimedia and communications systems. The recent surge in wireless and mobile computing underscores the need for high-performance low power DSP hardware. Reconfigurable hardware balances these requirements wit ..."

with development costs by providing system designers a viable alternative to custom integrated circuits. This paper describes a novel reconfigurable architecture for DSP applications. The device contains an array of medium-grain cells that can perform arithmetic, memory, and control operations. The main features
Delgado-Frias, “Fault avoidance in medium-grain reconfigurable hardware architectures
- in International Conference on Engineering of Reconfigurable Systems and Algorithms
"... Abstract—Medium-grain reconfigurable hardware (MGRH) architectures represent a hybrid between the versatility of a field programmable gate array (FPGA) and the computational power of a custom application-specific integrated circuit (ASIC) [1]. Recent research has shown that they are particularly app ..."

This means that medium-grain reconfig-urable architectures have a high potential for implementation in mobile computing platforms, wireless sensor networks, military technology, and aerospace applications
Providing Structure for Medium-grained Distributed Object-based Computation
"... Pipelined Processor Farms (PPF) are a generic parallelprocessing structure suitable for continuous-flow, multialgorithm applications. PPF has been redesigned for a multimedia workload which is multifunctional and multimodal. A dynamic object-based processing structure is implemented which will map o ..."

Optimizing Irregular Adaptive Applications on Multi-threaded Processors: The Case of Medium-Grain Parallel Delaunay Mesh Generation
, 2006
"... The Importance of parallel mesh generation and emerging growth of SMT architectures raise an important question of adapting parallel mesh generation software to the SMT ar-chitecture. In this work we focus on Parallel Constrained Delaunay Mesh Generation. We explore medium grain parallelism at the s ..."

The second contribution is that we significantly improved the performance of the PCDT software using the optimizations developed for the MPCDT code and the SMT architecture. These changes made PCDT
Optimizing Parallel Applications for Wide-Area Clusters
- IN IPPS-98 INTERNATIONAL PARALLEL PROCESSING SYMPOSIUM
, 1998
"... Recent developments in networking technology cause a growing interest in connecting local-area clusters of workstations over wide-area links, creating multilevel clusters, or meta computers. Often, latency and bandwidth of local-area and wide-area networks differ by two orders of magnitude or more. ..."

. One would expect only very coarse grain applications to achieve good performance. To test this intuition, we analyze the behavior of several existing medium-grain applications on a wide-area multicluster. We find that high performance can be obtained if the programs are optimized to take
Adaptive Sampling-Based Profiling Techniques for Optimizing the Distributed JVM Runtime
"... Abstract—Extending the standard Java virtual machine (JVM) for cluster-awareness is a transparent approach to scaling out multithreaded Java applications. While this clustering solution is gaining momentum in recent years, efficient runtime support for fine-grained object sharing over the distribute ..."

Improving the Performance of Speculatively Parallel Applications on the Hydra CMP
, 1999
"... Hydra is a chip multiprocessor (CMP) with integrated support for thread-level speculation. Thread-level speculation provides a way to parallelize sequential programs without the need for data dependence analysis or synchronization. This makes it possible to parallelize applications for which static ..."

memory dependence analysis is difficult or impossible. While performance of the baseline Hydra system on applications with significant amounts of medium to large grain parallelism is good, the performance on integer applications with fine-grained parallelism can be poor. In this paper, we describe a
Impact of Sharing-Based Thread Placement on Multithreaded Architectures
